VelocitySensor

Measures the ideal absolute angular velocity of a rotational mechanical flange.

This sensor provides an ideal measurement of the absolute angular velocity of a connected rotational flange. It computes the angular velocity by taking the time derivative of the absolute angular position, $\text{spline}.\phi$, of the flange. The angular position $\text{spline}.\phi$ is accessed via a spline connector. The defining equation for the output angular velocity $w$ is:

\[w = \frac{d(\\phi_{spline})}{dt}\]

This component extends from PartialAbsoluteSensor

Usage

RotationalComponents.VelocitySensor()

Connectors

• spline - This connector represents a rotational spline with angle and torque as the potential and flow variables, respectively. (Spline)
• w - This connector represents a real signal as an output from a component (RealOutput)

Behavior

\[ \begin{align} 0 &= \mathtt{spline.tau}\left( t \right) \\ w\left( t \right) &= \frac{\mathrm{d} \mathtt{spline.phi}\left( t \right)}{\mathrm{d}t} \end{align} \]
